edit_curv - interactive graphic curve editor

### Calling Sequence

  `[x,y,ok,gc] = edit_curv(y)`
  `[x,y,ok,gc] = edit_curv(x,y)`
  `[x,y,ok,gc] = edit_curv(x,y,job)`
  `[x,y,ok,gc] = edit_curv(x,y,job,tit)`
  `[x,y,ok,gc] = edit_curv(x,y,job,tit,gc)`

### Parameters

- `x`: vector of x coordinates
- `y`: vector of y coordinates
- `job`: a character string formed by one to three of the characters 'a','x','y'
  - `'a'`: to add points to the edited curve
  - `'x'` : to modify x coordinates of the edited curve points
  - `'y'` : to modify y coordinates of the edited curve points
- `tit`: a vector of three character strings which give the curve legend
- `gc`: a list of graphic window parameters: `gc=list(rect,nax)`
  - `rect`: bounds of the graphics (see plot2d for details)
  - `nax`: graduation parameters (see plot2d for details)
- `ok`: indicator if ok==%t user as returned with 'ok' menu else user as returned with 'abort' menu : list (graphical objects created under `edit_curv`

### Description
